Tip about push to create project

Release in GitLab %10.5, you can push to create a project https://gitlab.com/gitlab-org/gitlab-ce/issues/26388 but there is no tip in the interface so that users discover this. We should add a tip to the New Project interface.

Proposal

On the “New project” page, add a tip to the page description indicating they can push to create a new project:

Idle	On press

This is using our popover pattern.

Tip: You can also create a project from the command line. Show command

Push to create a project

Private projects can be created in your personal namespace with:

git push git@gitlab.com:jramsay/$(git rev-parse --show-toplevel | xargs basename)
